π cik_vm_init(9) π
okay bestie, welcome to the Kernel API Manual β¨ this one's a little kernel callback and honestly she's serving "quietly essential" β let's get into it π«Ά
πΈ NAME πΈ
cik_vm_init β cik vm init callback π«
β¨ SYNOPSIS β¨
int cik_vm_init (struct radeon_device *rdev );
literally that's it. no cap. π
π¦ ARGUMENTS π¦
rdevβ aradeon_devicepointer, iykyk π
π₯ DESCRIPTION π₯
so what does she do? she inits cik specific vm parameters β that's the number of VMs, and the base of vram for VMIDs 1-15 β all in the CIK context π
and the flex? she returns 0 for success. that's it, that's the whole win, periodt β¨
